According to a third-party verification report from China General Certification Center (CGC), LONGi’s Hi-MO 9 BC modules were found to deliver a significant performance advantage over TOPCon modules in an outdoor field test conducted in Sanya City, Hainan Province.
The test site, located in Yazhou District, included 4 module arrays (20 Hi-MO 9 and 20 TOPCon modules) under different shading conditions. Results collected from October to December 2024 show that the Hi-MO 9 modules, based on LONGi’s second-generation BC technology, achieved power generation gains of 0.75% under normal outdoor conditions, 32.62% under partial shading, and 11.34% under column shading compared to TOPCon modules.
LONGi recently also released test data from a test site in Shandong Province, which showed its Hi-MO 9 modules delivering an average power generation gain of 2.93% over TOPCon modules and 5.92% over HJT modules from September to November 2024 (see China Solar PV News Snippets).
At the recent TaiyangNews High-Efficiency Solar Technologies Conference 2024, ISC Konstanz’s Radovan Kopecek said that BC technology is expected to reach an average mass-scale efficiency of 25.5% in the next 7 years (see ISC Konstanz: BC Technology The Right Successor To TOPCon).
Conversely, HJT manufacturer Huasun Energy shared field test data comparing HJT and BC modules at the CTC National Inspection Group Mohe Test Base, which showed HJT modules’ energy yield was about 7% higher than BC modules (see China Solar PV News Snippets).
Tongwei New Energy, a subsidiary of Tongwei Group, has signed an agreement with the Jintang County Government in Sichuan Province to develop a 150 MW/300 MWh shared energy storage project as part of an integrated energy system. This RMB 500 million ($68.49 million) initiative will be Sichuan’s first cross-regional integrated energy demonstration project, incorporating advanced lithium iron phosphate (LFP) battery storage and an intelligent energy management system.
Recently, Tongwei was named the winner of the solar module procurement for the Chacheng Mine subsidence area PV power project (see China Solar PV News Snippets).
Leading solar PV and ESS manufacturer JinkoSolar, in collaboration with the Clean Energy Technology Research Institute under China Huaneng, and other domestic and international institutions, has spearheaded the development of an international standard titled Accessibility Assessment for Installation and Maintenance of Glass PV Module Integrated with Roof (ISO/IEC TS 25522). Officially approved for IEC project initiation, this standard aims to assess the walkability of solar PV modules during installation and maintenance. JinkoSolar stated that this initiative will fill a global gap in the evaluation of solar module resistance to foot traffic, particularly in the distributed solar sector. The standard is currently undergoing RVN document processing and is expected to be submitted as a Committee Draft (CD) to the IEC Standardization Committee for public consultation by mid-2025.
On the IP front, JinkoSolar has launched another patent infringement lawsuit, this time against Waaree Group (see JinkoSolar Files Patent Infringement Lawsuit Against India’s Waaree).
CNNP Optoelectronics Technology (Shanghai) Co., Ltd., has submitted an environmental impact report to the Shanghai Municipal Bureau of Ecology and Environment for the first phase of its 200MW perovskite module pilot production line. The company is a joint venture between China National Nuclear Corporation (CNNC) and the Chinese Academy of Sciences. In its first phase, the company plans to build a 100 MW rigid perovskite module production line, set to commence construction in February 2025 with production expected to start by September 2025. CNNP previously built a MW-scale roll-to-roll flexible perovskite pilot line in 2023, capable of continuously producing 100-meter-long flexible perovskite modules. In 2024, the company claimed it had set a record for flexible perovskite module efficiency, achieving 17.75% for a 1200 × 400 mm module.
China Datang has launched the bidding process for its 2025–2026 solar PV module framework procurement, totaling 22.5 GW. It includes 19.5 GW of TOPCon modules, 2 GW of HJT modules, and 1 GW of BC modules. According to local media, 44 companies have submitted bids for the TOPCon segment, with price offers ranging from RMB 0.66 ($0.091) to RMB 0.832/W ($0.114/W) for an average of RMB 0.696/W ($0.096/W). 12 companies bid for the HJT segment, with prices between RMB 0.685 ($0.094) and RMB 0.979/W ($0.135/W) for an average of RMB 0.763/W ($0.105/W). The BC segment received bids from 5 companies, with prices ranging from RMB 0.73 ($0.100) to RMB 1.127/W ($0.155/W) for an average of RMB 0.839/W ($0.115/W).
